Somewhere on the frontier between thought and reality exists the Discworld, a parallel time and place that might sound and smell very much like our own, but which looks completely different. Particularly as it’s carried though space on the back of a giant turtle (sex unknown). It plays by different rules. But then, some things are the same everywhere. The Disc’s very existence is about to be threatened by a strange new blight: the world’s first tourist, upon whose survival rests the peace and prosperity of the land.

A nightmarish danger threatens from the other side of reality. . . . Armed with only a frying pan and her common sense, young witch-to-be Tiffany Aching must defend her home against the monsters of Fairyland. Luckily she has some very unusual help: the local Nac Mac Feegle—aka the Wee Free Men—a clan of fierce, sheep-stealing, sword-wielding, six-inch-high blue men.

The Western Front, 1916. Private Percy Blakeney wakes up. He is lying on fresh spring grass. He can hear birdsong and the wind in the leaves. Where have the mud, blood, and blasted landscape of no-man's-land gone? For that matter, where has Percy gone? Madison, Wisconsin, 2015. Police officer Monica Jansson is exploring the burned-out home of a reclusive - some say mad, others allege dangerous - scientist who seems to have vanished. Sifting through the wreckage, Jansson find a curious gadget.

A delightfully funny, fantastically inventive collection of twenty unearthed short stories by Sir Terry Pratchett, the award-winning and bestselling author and creator of the phenomenally successful Discworld fantasy series. These rediscovered tales were written by Terry Pratchett under a pseudonym for British newspapers during the 1970s and 1980s. The stories have never been attributed to him until now, and might never have been found—were it not for the efforts of a few dedicated fans.

Thirteen-year-old Mau is the only one left after a giant wave sweeps his island village away. But when much is taken, something is returned, and somewhere in the jungle, Daphne - a girl from the other side of the globe - is the sole survivor of a ship destroyed by the same wave.

In the beginning, there was nothing but endless flatness. Then came the Carpet.... Now, the Carpet is home to many different tribes and peoples, and a new story: the story of Fray, sweeping a trail of destruction across the Carpet; the story of power-hungry mouls - and of two Munrung brothers who set out on an adventure to end all adventures when their village is flattened. It's a story that will come to a terrible end if someone doesn't do something about it.

Terry Pratchett has earned a place in the hearts of listeners the world over with his best-selling Discworld series - but in recent years he has become equally well-known and respected as an outspoken campaigner for causes including Alzheimer's research and animal rights. A Slip of the Keyboard brings together for the first time the finest examples of Pratchett's nonfiction writing, both serious and surreal: from musings on mushrooms to what it means to be a writer (and why banana daiquiris are so important).

To the thousands of tiny nomes who live under the floorboards of a large department store, there is no outside. Things like day and night, sun and rain are just daft old legends. Then a devastating piece of news shatters their existence: the Store, their whole world, is to be demolished.

The Witch's Vacuum Cleaner and Other Stories is the second fabulously funny short story collection from the late acclaimed storyteller Terry Pratchett. A follow-up to Dragons at Crumbling Castle, this second batch of storytelling gems features stories written when Sir Terry was just 17 years old and working as a junior reporter. In this audiobook new Pratchett fans will find wonder, mayhem, sorcery, and delight - and loyal listeners will recognize the seeds of ideas that went on to influence his most beloved tales later in life.

A wonderful collection of short stories by master storyteller Sir Terry Pratchett, featuring dragons, dinosaurs, cavemen and car races! Dragons have invaded Crumbling Castle, and all of King Arthur's knights are either on holiday or visiting their grannies. It's a disaster! Luckily, there's a spare suit of armour and a very small boy called Ralph who's willing to fill it. Together with Fortnight the Friday knight and Fossfiddle the wizard, Ralph sets out to defeat the fearsome fire-breathers.

At six years old, Terry was told by his headteacher that he would never amount to anything. He spent the rest of his life proving that teacher wrong. At 66, Terry had lived a life full of achievements: becoming one of the UK's best-selling writers, winning the Carnegie Medal and being awarded a knighthood for services to literature. Following his untimely death from Alzheimer's disease, the mantle of completing Terry's memoir was passed to Rob Wilkins, his former assistant, friend and now head of the author's literary estate.

Sir Terry Pratchett was a much-loved writer who gained international fame for his Discworld fantasy series. In this recording we hear—in his own words—about science-fantasy and comedy writing. He discusses his fans and followers, how he enjoys writing and the importance of the Discworld characters. We hear his thoughts on fame and isolation, his attitude to money and about his reaction to diagnosis with early-onset Alzheimer's disease.

The number-one New York Times best-selling author of Small Great Things returns with a powerful and provocative new novel about ordinary lives that intersect during a heart-stopping crisis. The warm fall day starts like any other at the Center - a women’s reproductive health services clinic. Then, in late morning, a desperate and distraught gunman bursts in and opens fire, taking all inside hostage.

Contains books one and two of the Attempted Vampirism series: Attempted Vampirism and Attempted Adventuring.

World-renowned Harvard symbologist Robert Langdon is summoned to a Swiss research facility to analyze a cryptic symbol seared into the chest of a murdered physicist. What he discovers is unimaginable: a deadly vendetta against the Catholic Church by a centuries-old underground organization, the Illuminati. Desperate to save the Vatican from a powerful time bomb, Langdon joins forces in Rome with the beautiful and mysterious scientist Vittoria Vetra.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

Throughout history, scientists have come up with theories and ideas that just don't seem to make sense. These we call paradoxes. The paradoxes Al-Khalili offers are drawn chiefly from physics and astronomy and represent those that have stumped some of the finest minds. With elegant explanations that bring the listener inside the mind of those who've developed them, Al-Khalili helps us to see that, in fact, paradoxes can be solved if seen from the right angle.

In Beyond Biocentrism, acclaimed biologist Robert Lanza and astronomer Bob Berman take the listener on an intellectual thrill ride as they reexamine everything we thought we knew about life, death, the universe, and the nature of reality itself. The first step is acknowledging that our existing model of reality is looking increasingly creaky in the face of recent scientific discoveries.

The late great astronomer and astrophysicist describes his personal search to understand the nature of the sacred in the vastness of the cosmos. Exhibiting a breadth of intellect nothing short of astounding, Sagan presents his views on a wide range of topics, including the likelihood of intelligent life on other planets, creationism and so-called intelligent design.

A unique fusion of philosophy and metaphysics set against the backdrop of contemporary culture. Have you ever wondered if the world is really there when you're not looking? We tend to take the reality of our world very much for granted. This book will lead you down the rabbit hole in search of something we can point to, hang our hats on, and say this is real.

How much can we know about the world? In this audiobook physicist Marcelo Gleiser traces our search for answers to the most fundamental questions of existence, the origin of the universe, the nature of reality, and the limits of knowledge. In so doing he reaches a provocative conclusion: Science, like religion, is fundamentally limited as a tool for understanding the world. As science and its philosophical interpretations advance, we face the unsettling recognition of how much we don't know.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

What is space? It isn't a question that most of us normally stop to ask. Space is the venue of physics; it's where things exist, where they move and take shape. Yet over the past few decades, physicists have discovered a phenomenon that operates outside the confines of space and time. The phenomenon - the ability of one particle to affect another instantly across the vastness of space - appears to be almost magical.

Far too often, public discussion of science is carried out by journalists, voters, and politicians who have received their science secondhand. The Story of Western Science shows us the joy and importance of reading groundbreaking science writing for ourselves and guides us back to the masterpieces that have changed the way we think about our world, our cosmos, and ourselves.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

In this fascinating and illuminating work, Leonard Mlodinow guides us through the critical eras and events in the development of science, all of which, he demonstrates, were propelled forward by humankind's collective struggle to know. From the birth of reasoning and culture to the formation of the studies of physics, chemistry, biology, and modern-day quantum physics, we come to see that much of our progress can be attributed to simple questions - why? how? - bravely asked.

In trying to understand the atom, physicists built quantum mechanics, the most successful theory in science and the basis of one-third of our economy. They found, to their embarrassment, that with their theory, physics encounters consciousness. Authors Bruce Rosenblum and Fred Kuttner explain all this in nontechnical terms with help from some fanciful stories and anecdotes about the theory's developers. They present the quantum mystery honestly, emphasizing what is and what is not speculation.

A physicist speeds across space, time, and everything in between showing that our elegant universe from the Higgs boson to antimatter to the most massive group of galaxies is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper-drive tour of the universe like this one.

On March 21, 2013, the European Space Agency released a map of the afterglow of the big bang. Taking in 440 sextillion kilometers of space and 13.8 billion years of time, it is physically impossible to make a better map: We will never see the early universe in more detail. On the one hand, such a view is the apotheosis of modern cosmology; on the other, it threatens to undermine almost everything we hold cosmologically sacrosanct.

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.
